Referring to fig. 9 and 10, a plurality of air chambers 4101 are uniformly distributed in the rod 41, the plurality of air chambers 4101 are uniformly distributed on two sides of the magnetic ball 42, a plurality of uniformly distributed air flow channels 4102 are further formed in the rod 41, the plurality of air flow channels 4102 are respectively located between a pair of adjacent air chambers 4101, the air chambers 4101 are communicated with the air flow channels 4102, flared air release grooves 4104 are formed in two end portions of the rod 41, a slide way 4103 communicated with the adjacent air chamber 4101 is formed in the inner wall of the flared air release groove 4104, a bidirectional flow control valve is arranged in the slide way 4103, when the rod 41 is gathered at a bending point, on one hand, a large bending resistance is provided for the present invention through the plurality of rods 41, the bending degree of the sheath 1 and the cable core 2 is reduced, on the other hand, when an external bending force reaches a high strength, the bending resistance of the rod 41 can be reduced suddenly through the cooperation of the air chambers 4101 and the bidirectional flow control valve, the sheath 1, the cable core 2 and the rod body 41 are bent appropriately, so that the cable has certain flexibility, is suitable for large external acting force, and is convenient to use.
Referring to fig. 11 and 12, the bidirectional flow control valve includes an opening cylinder 8, the opening cylinder 8 is slidably connected to the inside of the slideway 4103, a screen 10, a compression spring 11 and a sealing ball 12 are disposed inside the opening cylinder 8, the screen 10, the compression spring 11 and the sealing ball 12 are sequentially distributed along a direction away from the air cavity 4101, an outer end of the screen 10 is fixedly connected to an inner wall of the opening cylinder 8, an outer end of the opening cylinder 8 is provided with a plurality of uniformly distributed air outlets 801, the air outlets 801 are located between the screen 10 and the air cavity 4101, one end of the opening cylinder 8 away from the air cavity 4101 is provided with an air inlet 802, a diameter of the sealing ball 12 is larger than an aperture of the air inlet 802, when no external force is applied, the sealing ball 12 is pressed against an aperture of the air inlet 802 to seal the air inlet 802, and under the cooperation of the screen 10, the compression spring 11 and the sealing ball 12, the air flow flows unidirectionally at the air inlet 802, the specific situation is as follows: when air flow moves along the direction from the air cavity 4101 to the flaring air release groove 4104, after the air enters the inside of the opening tube 8, the pressure generated on the sealing ball 12 is the same as the elastic force direction of the compression spring 11, so that the sealing ball 12 is always sealed at the air inlet hole 802, namely when the air cavity 4101 is extruded, the air in the air cavity is not easy to flow out through the air inlet hole 802; when the airflow direction is opposite to the above, the pressure of the airflow on the sealing ball 12 is opposite to the elastic force direction of the compression spring 11, so that the compression spring 11 contracts, the sealing ball 12 moves out of the air inlet hole 802, and the outside airflow can enter the air cavity 4101 through the air inlet hole 802.
Referring to fig. 11 and 12, an inner ring 7 is fixedly connected to the inside of the slide 4103, the inner ring 7 is located between the open cylinder 8 and the air chamber 4101, a plurality of uniformly distributed elastic bands 9 are fixedly connected between the inner ring 7 and the open cylinder 8, and the air outlet 801 is located inside the slide 4103 in an initial state, that is: when the elastic band 9 is at the initial length, the air outlet 801 is located inside the slideway 4103, when the rod 41 bends along with the sheath 1 and the cable core 2, because the rod 41 is in a bending and pressing state, the air pressure inside the air cavity 4101 increases, the air enters the open cylinder 8, and the air inlet 802 allows the air flow to flow in one direction from outside to inside, so the excessive air pressure inside the open cylinder 8 is difficult to flow out from the air inlet 802, as the air pressure inside the open cylinder 8 increases, the elastic band 9 is elongated, the open cylinder 8 gradually moves towards the inner side of the flared air release groove 4104 until the air outlet 801 moves out of the slideway 4103, at this time, the air inside the air cavity 4101 can enter the flared air release groove 4104 through the air outlet 801, and then the rod 41 is discharged, the bending resistance of the rod 41 is weakened, and the bending and flattening along with the sheath 1 and the cable core 2 under the pressure can be more smoothly performed, so that the cable has certain flexibility, the bending is carried out by adapting to the external acting force. When the external force disappears, the rod 41 automatically recovers to the straight state, and because the inside of the air chamber 4101 presents negative pressure, the air outside the rod 41 can extrude the sealing ball 12 inwards, and enters the inside of the air chamber 4101 through the air inlet 802, and the rod 41 recovers to the roundness.
The invention arranges the bending-resistant screw rod sleeve between the sheath 1 and the cable core 2, when the invention is subjected to bending force in any direction, the sheath 1 and the cable core 2 are bent, the bending-resistant elastic rods 4 which are originally uniformly distributed and arranged can gradually move to the vicinity of the bending point due to the self length limitation and are intensively gathered at the bending point to jointly provide acting force for the cable core 2 to resist bending, thereby the invention has larger bending resistance, and after the external bending force disappears, the bending-resistant elastic rods 4 automatically disperse to provide resilience force for the sheath 1 and the cable core 2 to recover linear shape, so that the invention can recover the linear state more quickly and effectively, reduce the bending damage degree of the cable core 2, in addition, when the external bending force reaches a higher force, the bending-resistant elastic rods 4 automatically release gas outwards, reduce the self bending resistance, and generate moderate bending along with the sheath 1 and the cable core 2, the invention has certain flexibility, is suitable for external larger acting force and is convenient to use.
The above; but are merely preferred embodiments of the invention; the scope of the invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; the technical scheme and the improved concept of the invention are equally replaced or changed; are intended to be covered by the scope of the present invention.
